Product details
Overview
MMBZ27VCL from Nexperia is a unidirectional double ESD protection diode in common-cathode SOT23 configuration, designed for transient overvoltage suppression on up to two signal lines. It delivers 30 kV contact ESD immunity (IEC 61000-4-2 Level 4), clamps at ≤38 V under 1 A 10/1000 µs surge, and exhibits ≤48 pF capacitance at 1 MHz with ≤5 nA leakage at 22 V standoff.
For engineers reviewing the MMBZ27VCL datasheet, MMBZ27VCL pinout, MMBZ27VCL application, or MMBZ27VCL equivalent, this device is selected for high-speed data line protection where low capacitance, precise clamping, dual-line coverage, and IEC-compliant ESD robustness are required in space-constrained SMT designs.
Technical Context
The MMBZ27VCL integrates two identical unidirectional Zener-like ESD protection diodes sharing a common cathode terminal, enabling independent protection of two positive-polarity signal lines referenced to ground. Its breakdown voltage is tightly specified at 27 V (±5%), with clamping voltage guaranteed ≤38 V at 1 A peak pulse current per diode.
It operates under IEC 61643-321 surge conditions (10/1000 µs waveform) and meets IEC 61000-4-2 Level 4 ESD requirements. Thermal resistance from junction to ambient is 350 K/W on standard FR4, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 22 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected lines. |
| Breakdown Voltage | 27 V (typical), 25.65–28.35 V - Precise Zener threshold triggering clamping action during transients. |
| Clamping Voltage | ≤38 V at 1 A, 10/1000 µs - Limits voltage seen by downstream ICs during surge events. |
| Diode Capacitance | 48 pF (typical) at 1 MHz, 0 V - Enables use on USB 2.0, HDMI, and other high-speed interfaces without signal integrity degradation. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2 Level 4) - Validates robustness against human-body ESD events in end-user environments. |
| Leakage Current | ≤5 nA at 22 V - Minimizes DC loading on sensitive analog or low-power signal paths. |
| Peak Pulse Power | 40 W (10/1000 µs) - Supports energy absorption for transient surges per IEC 61643-321 compliance. |
Pinout & Package
Encapsulated in a SOT23 (TO-236AB) surface-mount plastic package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch, the MMBZ27VCL uses a standardized 3-terminal footprint compatible with automated reflow and wave soldering per Nexperia's sot023_fr and sot023_fw footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input connection for first protected signal line; conducts to common cathode during overvoltage. |
| 2 | Anode (Diode 2) | Input connection for second protected signal line; electrically isolated from Pin 1, shares cathode return path. |
| 3 | Common Cathode | Shared ground reference node for both diodes; must be connected to system ground with minimal inductance for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Two independent anodes allow simultaneous safeguarding of separate positive-referenced signals (e.g., USB D+ and D−) using one component. |
| Bidirectional single-line capability | Configurable as a bidirectional protector by grounding one anode and using the other anode + common cathode across a differential pair. |
| Low 48 pF capacitance | Preserves signal rise/fall times on interfaces up to 480 Mbps (e.g., full-speed USB), minimizing jitter and bit errors. |
| 30 kV contact ESD immunity | Exceeds industrial and consumer IEC 61000-4-2 Level 4 requirements without external circuitry or layout compromises. |
| Ultra-low 0.1 nA typical leakage | Prevents measurable DC offset or battery drain in always-on sensor or audio bias networks. |
Applications
| USB Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines from ESD events during cable insertion or handling in portable peripherals. IC Role / Device Role / Timing Role: Unidirectional clamping diode array placed at connector entry point to shunt transients before reaching USB transceiver IC. Use Value: 48 pF capacitance avoids signal integrity loss at 480 Mbps; 30 kV ESD rating ensures compliance with IEC 61000-4-2 without derating. |
Use Scenario: Safeguarding HDMI TMDS clock and data channels against ESD in AV receivers and set-top boxes. IC Role / Device Role / Timing Role: Dual-channel ESD suppressor mounted adjacent to HDMI receptacle to clamp fast-rising transients before HDMI PHY input pins. Use Value: Low capacitance preserves edge fidelity across 3.4 Gbps links; 22 V standoff accommodates HDMI DC bias levels. |
| Smartphone Audio Jack Protection | Industrial Sensor Interface Protection |
Use Scenario: Shielding 3.5 mm TRRS headset jack lines (MIC, L/R, GND) from user-induced ESD in handheld devices. IC Role / Device Role / Timing Role: Common-cathode dual diode routing MIC and stereo audio lines to shared ground plane while maintaining channel isolation. Use Value: 5 nA max leakage prevents microphone bias distortion; compact SOT23 fits tight board real estate near jack footprint. |
Use Scenario: Protecting RS-485 or CAN FD transceiver inputs from lightning-induced surges in factory automation nodes. IC Role / Device Role / Timing Role: Front-end transient suppressor on differential bus lines, leveraging bidirectional mode via anode-to-anode configuration. Use Value: 40 W peak power rating handles multi-kV surges; 150 °C max junction temperature supports operation in uncooled enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP2114 | Lower 17 V standoff, higher 100 pF capacitance, same SOT23-3 package. | Better suited for lower-voltage logic (e.g., 3.3 V GPIO), less ideal for 5 V or analog signal lines due to higher capacitance. | Select when protecting sub-20 V digital I/O with relaxed speed requirements and cost sensitivity. |
| Vishay ESDE0402-2 | 0402 chip-scale package (0.6 mm × 0.3 mm), 24 V standoff, 30 pF capacitance, 25 kV ESD rating. | Enables ultra-dense layouts but requires advanced assembly; lower ESD margin than MMBZ27VCL for contact discharge. | Choose for miniaturized wearables or medical sensors where board area is critical and 25 kV ESD suffices. |
Compared with NUP2114 and ESDE0402-2, the MMBZ27VCL offers the highest ESD immunity (30 kV), optimal balance of 22 V standoff and 48 pF capacitance for mixed-signal interfaces, and mature SOT23 manufacturability-making it preferred for mainstream consumer and industrial USB/HDMI/audio protection.

FAQ
What is the maximum clamping voltage of the MMBZ27VCL under surge conditions?
The MMBZ27VCL clamps to ≤38 V when subjected to a 1 A, 10/1000 µs exponential surge pulse per diode, measured from anode to common cathode. This value is guaranteed across temperature and process variation per IEC 61643-321 test conditions and ensures downstream ICs remain within absolute maximum ratings during transient events.
Can the MMBZ27VCL protect bidirectional signal lines like RS-485?
Yes-the MMBZ27VCL can be configured for bidirectional protection by connecting one anode to ground and using the second anode and common cathode across the differential pair. In this mode, it provides symmetrical clamping for ±15 V common-mode transients, validated per IEC 61000-4-2 air discharge (15 kV) and machine model (2 kV) tests.
How does the SOT23 package affect thermal performance in sustained surge scenarios?
Mounted on standard FR4 with single-sided copper, the MMBZ27VCL exhibits a junction-to-ambient thermal resistance of 350 K/W. Under repetitive 10/1000 µs pulses at 1 Hz, this allows safe dissipation of up to 40 W peak power without exceeding 150 °C junction temperature, provided PCB layout follows Nexperia's guidelines for short ground paths and thermal relief.
Is the MMBZ27VCL automotive qualified?
No-the MMBZ27VCL is not automotive qualified. Per Nexperia's revision history (v.2, April 2023), it was explicitly changed to non-automotive qualification. For automotive applications, Nexperia recommends its -Q qualified equivalents such as the PESD5V0S1BA (SOT23-3) or PESD5V0X1BC (SOD323), which undergo AEC-Q200 stress testing and extended temperature validation.
